• Wide Compatibility - The R134A self-sealing can tap refrigerant dispenser with tank adapter, and connects all R134A automotive air conditioning refrigerant cans. Refrigerant bottle opener with 1/2’’ ACME LH female/internal thread, the 1/4’’ SAE male/external cooling pipe connection thread can direct fitting for R12 R22 manifold. The 1/4’’ SAE female x 1/2’’ ACME male tank adapter fitting for the R134A manifold

• R134A Self-Sealing Can Tap Valve - This r134a self-sealing can tap designs with hand-operated punch/valve control, it can only be used for self-sealing cans with 1/2’’ ACME thread (Can capacity usual greater than 6OZ or so-called big cans), either cannot be used on puncture style cans

• Useful Tank Adapter - The R134A car air conditioning tank adapter comes with a 1/4" SAE female x 1/2" ACME male flare, which connects to the R134A manifold

• Premium Quality - This R134A refrigerant self-sealing can tap with adapter is made of heavy-duty brass alloy for durable use, with a screw-on design and safety check valve, even working under extreme conditions, features long-lasting seals to prevent leaking

Easy To Use:

• 1. Counterclockwise switch the T knob to retract the internal pin

• 2. Screw the can tap dispenser on R134a can open and hook it to R134a charging hose parts

• 3. Clockwise switch the T knob until the pin punctures the sweet spot of the bottle opening

• 4. Counterclockwise switch T knob, then R134a fill the hose and be charged into air conditioning

Top Up of R134a Refrigerant: 

• 1. You need some tools, like a digital manifold gauge set, can of r134a, can tap, digital thermometer, r134a adapter

• 2. Using a thick solution of dish washing liquid and water to figure out whether leak-free

• 3. With the can tap connected to the can of r134a hose, turn on the can tap valve a little to get the air purged out, and then turn off the blue valve on the manifold

• 4. With the car started and AC compressor on, recirculation mode, blower fan on max, slowly opened the blue valve to allow r134a into the system. Keep an eye on the low-pressure gauge. Patience is needed here to add r134a and let the system equalize then add some more
